Numerical simulation of the structure of NGC 1300 under a strong bar potential. The figures from left to right are the numerical result, observation, and their superposition, respectively.

The Computational Fluid Dynamics and Magnetohydrodynamics (CFD/MHD) group has developed a high performance code, Antares. The results of high resolution simulations show that, with a sufficiently strong bar potential, the straight dust lanes and a central star formation ring, similar to those seen in NGC 1300, can be generated in the process.
